Linear drive for space travel applications has folding bellows connected to actuator, fixed and movable end plates connected to bellows ends, tension spring elements and hydraulic system

摘要

The linear drive has a folding bellows (1) connected to an actuator (10), a fixed end plate (12) forming part of the structure (14) connected to one end of the bellows, a movable end plate (16) connected to the other end, tension spring elements (7) attached to both end plates and a hydraulic system that acts on the folding bellows with two pressure containers, two precision needle valves, pressure lines to the bellows and lines from the bellows.
